A fire detection system and detection method based on video image processing

Abstract

The invention discloses a fire detection system and detection method based on video image processing. It consists of a video acquisition module, a fire detection module, a fire analysis module, a fire judgment module and a fire alarm module connected in turn. The video acquisition module collects video images in the area covered by the camera; the fire detection module performs background modeling and background update on the video image, and detects moving objects in the foreground; the fire analysis module analyzes the video image to find out the suspected flame area, and extracts The static and dynamic features of the suspected flame; the fire judgment module uses the static and dynamic features of the flame extracted by the fire analysis module as the input of the BP neural network to judge whether there is a flame in the video; the fire alarm module will use the fire judgment module Output the result to judge whether to issue an alarm. The present invention combines the existing monitoring system to save detection cost and greatly reduces the false alarm rate on the basis of ensuring the accuracy of fire detection.

Description

technical field [0001] The invention relates to a fire detection system and a detection method, in particular to a fire detection system and a detection method based on video image processing. Background technique [0002] The economic loss caused by fire in modern life is very serious, and it greatly endangers the personal safety of human beings. Safety accidents such as high-rise building fires, forest fires, tunnel fires, and public transport fires are particularly prominent. When traditional fire detectors (smoke-sensing, temperature-sensing, etc.) detect the above-mentioned fires, the reaction time is too long and the false alarm rate is high, which is not conducive to the timely detection of fires. [0003] In modern times, with the development of computer technology and the maturity of video processing technology, video-based fire detection technology has also become an important method for detecting fire. However, due to the novelty of this technology and the high ...

Problems solved by technology

However, due to the novelty of this technology and the high cost of popularization in actual work, it is not widely used in practice. Those who have already applied this technology are also exposed to environmental and suspected flame disturbances during the implementation process. Influenced by the influence, there is also the disadvantage of high false alarm rate
